67e83b07c6 Fix information leak. We can find PIDs of running processes from within
a jail, etc. by simply calling setpriority(PRIO_PROCESS, <PID>, 0) and
checking the return value: 0 means that the process exists and -1 that
it doesn't exist.

ec96dca788 Simplify the inner loop of vm_fault()'s delete-behind heuristic.
Instead of checking each page for PG_UNMANAGED, perform a one-time
check whether the object is OBJT_PHYS.  (PG_UNMANAGED pages only
belong to OBJT_PHYS objects.)

dd3af71f17 Remove trailing ';' from C_SYSINIT() macro definition, in keeping
with style(9) recommendation that macros not contain the
terminating ';', leaving that to the invoker.  All SYSINIT()
consumers must now provide a trailing ';'.

Unlike the change to remove the ';'s from callers, this change
shouldn't be MFC'd unless we don't mind requiring source changes
to third party modules that might still depend on SYSINIT()
providing its own ';'.

237fdd787b In keeping with style(9)'s recommendations on macros, use a ';'

lightweight C parsers much happier with the FreeBSD kernel
source, including cflow's prcc and lxr.

60617bf578 A subtle point: "pax interchange format" mandates that all strings
(including pathname, gname, uname) be stored in UTF-8.  This usually
doesn't cause problems on FreeBSD because the "C" locale on FreeBSD
can convert any byte to Unicode/wchar_t and from there to UTF-8.  In
other locales (including the "C" locale on Linux which is really
ASCII), you can get into trouble with pathnames that cannot be
converted to UTF-8.

Libarchive's pax writer truncated pathnames and other strings at the
first nonconvertible character.  (ouch!)  Other archivers have worked
around this by storing unconvertible pathnames as raw binary, a
practice which has been sanctioned by the Austin group.  However,
libarchive's pax reader would segfault reading headers that weren't
proper UTF-8.  (ouch!)  Since bsdtar defaults to pax format, this
affects bsdtar rather heavily.

To correctly support the new "hdrcharset" header that is going into
SUS and to handle conversion failures in general, libarchive's pax reader
and writer have been overhauled fairly extensively.  They used to do
most of the pax header processing using wchar_t (Unicode); they now do
most of it using char so that common logic applies to either UTF-8 or
"binary" strings.

As a bonus, a number of extraneous conversions to/from wchar_t have
been eliminated, which should speed things up just a tad.

35ebab0a33 - Check device masks and bypass printing headers if capable device does
not exist.  /etc/rc.d/mixer tried to restore non-existent recording
source because /var/var/db/mixer*-state contains '=rec' for example.
- Remove hardcoded mixer2 and mixer3 and do the right thing.
- Replace getopt(3) with hand-rolled option parser.  It was not able
to handle 'mixer -rec mic' although it is a valid command.
- Make '-s' and '-S' mutualy exclusive as mixer(8) says.
- Do not re-read recording source unless it has been modified.

6c8f54e991 Don't advertise the default block size as a constant; don't
rely on a deprecated value to set the default.  This is also
related to a longer-term goal of setting the default block
size based on format and possibly other factors, which makes
it a bad idea to tie this to a published constant.

42d1f7b4ba Rework the versioning implementation and test to match the
new interface.  Mark the functions that are going away in
libarchive 3.0.

In particular, archive_version_string() now computes the
string rather than assuming that it will be created by the
build infrastructure.  Eventually, this will allow some
simplification of the build infrastructure.
